Mark;

I start cooling the camera 1.5 to 2 hours before I begin shooting anything (including darks), especially if it's been hot (it was  up to +39°C this week in the sun according to my personal weather station). To get the camera to cool faster, I leave it unplugged so it has no power and can't heat up. I leave it continually cooling while I'm shooting too.

HTH..

Milton,

You`ve made that somewhat clearer & more precise now. For those 140 (is it) 2 minute exposures you`re taking of Eros do you use the Peltier cooler or does the heat dissipate sufficiently between exposures. Does each exposure begin directly the last is completed? I guess Eros isn`t visible from my location or the time frame has changed as it`s not on my ST3 list at present.
